Unveiling a new waxwork of himself at Ireland's National Wax Museum, the Sinn Fein leader said some have also been calling him a bit of a dummy for years.

"Who knows?" he said, when asked if this was his only other identity.

The likeness was unveiled as part of a permanent exhibition apparently marking the signing of the Good Friday Agreement in 1998.

Until now the republican leader, who played a prominent role in the historic accord, had been left out

Others, who played no part at all, were included, noted Mr Adams at the launch.

Sculptures of the former DUP leader Ian Paisley, SDLP founder and Nobel peace laureate John Hume, ex-Irish premiers Bertie Ahern and John Bruton as well former Prime Minister John Major make up the display.

It is housed in the vault of a former bank off Dublin's Dame Street next to the museum's Chamber of Horrors dungeon.

"Ian Paisley, of course, famously wasn't part of the Good Friday Agreement, neither was John Bruton," said the Sinn Fein leader.

"John Major was handed a peace process on a plate, and he broke the plate."

He also pointed out the absence of Nobel laureate and Ulster Unionist leader David Trimble as well as the Women's Coalition.

Asked he liked the waxwork of himself, Mr Adams praised the painstaking work of the sculptor PJ Heraty.

"I think he has improved me, and, of course, I'm in need of much improvement," he said.
